Figure 7

Plots of raw horizontal total response force vectors for all perturbations in all directions in a normal rat (A) and an operate (B). Forces are plotted for the forelimb (FL) sensor, the right hindlimb (RHL) and left hindlimb (LHL) sensors. These combined data show that there is clear directional clustering of hindlimb forces in both the normals and the operate rats, but clustering of forelimbs directions occurs only in normal rats. In contrast, there is wide directional variability of forelimb forces in operates. This is consistent with forelimb compensation dominating the response adjustment used in operates, which requires force production in all directions in the forelimbs and small or negligible active force changes in the hindlimbs (see Figure 8).
